Time period:
Based on analysis utilizing <> techniques,
Use plot.ly for interactive plots ?
varImp for randomForest crashes in caret version:6.0.41 -> submit bug report
extensions toward multiclass classification are scheduled for the next release
glm_dmy_mdl should use the same method as glm_sel_mdl until custom dummy classifer is implemented

Null Hypothesis (\(\sf{H_{0}}\)): mpg is not impacted by am_fctr.
The variance by am_fctr appears to be independent. #{r q1, cache=FALSE} # print(t.test(subset(cars_df, am_fctr == "automatic")$mpg, # subset(cars_df, am_fctr == "manual")$mpg, # var.equal=FALSE)$conf) # We reject the null hypothesis i.e. we have evidence to conclude that am_fctr impacts mpg (95% confidence). Manual transmission is better for miles per gallon versus automatic transmission.
